How do I use threads in C++11 containers?

Can you explain how to use threads with C++11 containers?

Sure! In C++11, you can use the <thread> library to create threads and manage them. You can also use containers like std::vector or std::map to store data that threads can access.

What are some common issues when using threads with containers?

Common issues include data races, where multiple threads access shared data simultaneously, leading to inconsistent results. You can use mutexes to prevent this.

Can you give an example of using a mutex with a vector?

Absolutely! You can use std::mutex to lock access to a std::vector. Here's a simple example:

#include <vector>
#include <thread>
#include <mutex>

std::vector<int> myVector;
std::mutex vecMutex;

void addToVector(int value) {
    std::lock_guard<std::mutex> guard(vecMutex);
    myVector.push_back(value);
}

How do I ensure that all threads finish before the program exits?

You can use std::thread::join() to wait for each thread to finish executing before the main program continues. This ensures all threads complete their tasks.
